Re: Introducing the VeriSNES (FPGA-based SNES)
Yes, the low resolution composite output. Most modern LCD TVs are quite poor at upscaling 240p video. Also: it'd be great if Nintendo reissued "real" SNESs but that's just not going to happen. There just isn't a big enough market for original carts, and throwing a Linux emulator on an ARM ...

Re: How can I use dlls in Linux?
What’s a link command? is it the same as the #include<SDL2/SDL.h>? The link command looks more like something I would use in the shell, or whatever the Linux version of the command prompt is called. I have a pretty clear understanding of command prompt on Windows, but not the terminal on Linux. I h...

Re: Gameboy CPU instruction set timings and lengths
I can't speak authoritatively, but both the pandocs and the gambatte source code claim it's 12. It makes sense that they'd take less than RES (HL), or SET (HL) too, since they don't do any sort of writeback.

Re: Gameboy CPU instruction set timings and lengths
Regarding this Gameboy CPU (LR35902) Instruction Set table, the CB prefix is marked as 4 T-cycles, but the Prefix CB table cells contain their own timings. Does that mean that the total time is 4 + X T-cycles, where X comes from the Prefix CB table? No, it looks like the total time will be whatever...

Re: Introducing the VeriSNES (FPGA-based SNES)
Presumably (?) that'd add some lag, and one of the big reasons why people would want a hard-SNES/CRT combo is to minimize lag.

Re: "Mickey Mouse" 8-bit architectures
I love the 6502 - but one could easily argue that the 6502's register paucity, or its huge number of obviously "missing" instructions (push and pull X or Y, for instance), or the aspects of its design that make it a poor target for C compilers are similarly debilitating. The CMOS 6502 (65...

Re: Introducing the VeriSNES (FPGA-based SNES)
Happy they're doing it.
Sad it's not open source.
Disappointed by how bland it looks. Gimme brushed metal plz

Re: My Nintendo Wii experience
My favourite use of vibration is in Ico: your controller gently throbs when you hold Yorda's hand - it's supposed to be her pulse. It subtly makes her feel more "human" and helps make the player more emotionally invested in protecting her. Also, uh, Rez came with a pretty interesting hapti...

Re: Hypothetical non polygon based 3D?
Have a look at Ecstatica, a computer game sent to us from an alternate dimension where polygons do not exist (video in Polish for maximum otherworldliness).

Re: Is it possible to program Raspberry Pi in assembly?
Pfft, the 6502 is bloated. 56 instructions? What you really wanna learn is an OISC assembly language.

Re: Is it possible to program Raspberry Pi in assembly?
I wonder wether gcc is one of those "good compilers", or if they just made it "just work" with minimal care about hardcore optimisation. I'd lean toward the second possibility, considering it's free. GCC is a phenomenal compiler/optimizer. It's not quite as good as ICC, but is a...

Re: Is it possible to program Raspberry Pi in assembly?
Well, your terminology is slightly off, but sure, of course. What do you think the Pi does when it loads Linux or whatever other OS?if I have an assembled program on an SD card, plug it into the Raspberry Pi, will the bios load the assembly program into RAM and execute it as if it were a bios

Re: [SNES developer noob] Help me understand how sprites wor
IIRC (haven't touched the SNES in a bit): All writes go through a byte-sized port ($2104). When writing a word to the low table: 1. You write the low byte. It gets stored in a buffer. 2. You write the high byte. Only then is it written into the table. The low byte/high byte thing going on there refe...
